Since making his Bayern debut in 2007, Kroos has been earmarked as one of the hottest prospects in German football and went on to establish himself as a key member of the side a couple of years ago, after enjoying a successful loan spell at Bayer Leverkusen.
The 23-year-old was part of the side that won the Bundesliga, DFB-Pokal and UEFA Champions League last term but despite his impressive displays, the Bavarian outfit have yet to try and tie him down to a new deal.
And Kroos admits he could be tempted to try his luck abroad if there are no new developments with Bayern.
"There have been no negotiations," he told Bild. "That's why I don't have an answer to it right now.
"One thing is clear, I can imagine a lot of things. Let's wait and see.
"Abroad, the estimation for German players has risen enormously. If now three, four young German players make the switch, similar fees could be paid.
"That's a sign of quality - often those are young players, who have not reached the end of their development."
One player that Bayern have opened contract talks with is defender Jerome Boateng, who is optimistic an agreement will soon be reached.
"Yes," he told Kicker, when asked if both parties were close to meeting. "We are currently in talks.
"[The deal will be done] whenever we reach an agreement. For how long, I don't know."
Bayern are currently second in the Bundesliga after picking up ten points from their opening four games of the 2013/14 season.
